我的web界面有两个aspxGridView控件（这个是DevExpress中的控件），分别为ASPxGridView1、ASPxGridView2。我想在ASPXGridView1的ASPxGridView1_RowDeleting事件执行时重新绑定ASPxGridView2的数据源来刷新ASPxGridView2，但是没有成功！（ASPxGridView1的数据是可以刷新的）请高手指点下，代码如下：

 protected void ASPxGridView1_RowDeleting(object sender, DevExpress.Web.Data.ASPxDataDeletingEventArgs e)
        {
            try
            {
                DataTable dataTable = (DataTable)Session["dtPart"];
                e.Cancel = true;
                dataTable.PrimaryKey = new DataColumn[] { dataTable.Columns["SINo"], dataTable.Columns["BoschPN"] };
                dataTable.Rows.Remove(dataTable.Rows.Find(new object[] { e.Keys["SINo"].ToString(), e.Keys["BoschPN"].ToString() }));
                //还应该删除package表中的记录
                ASPxGridView1.DataSource = dataTable;
                ASPxGridView1.DataBind();
                DataTable dtPackage = (DataTable)Session["dtPackage"];
                DataRow[] rows = dtPackage.Select("BoschPN='" + e.Keys["BoschPN"].ToString() + "'");
                foreach (DataRow row in rows)
                {
                    dtPackage.Rows.Remove(row);
                }  

               ASPxGridView2.DataSource = dtPackage;
               ASPxGridView2.DataBind();              
             }
            catch (Exception ex)
            {

            }                      
        }
